Question

UserControl

作为上述简单测试的结果，我收到了很多启动噪音记录。在升级到spring-boot-2.x之前不是这种情况。如何防止这种噪音？

特别是，我的Intellij IDE将这些语句记录在 red 中，随着测试本身的通过，这更加令人困惑...

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT,
                    properties = "logging.level.root=OFF")
public class MyTest {
         @Test
         public void test() {}
}

也许必须使用log4j2吗？

Answer 1

已编辑

在测试资源（ \ test \ resources ）中创建 logback-test.xml ，然后将波纹管片段放入其中

<configuration>
    <include resource="org/springframework/boot/logging/logback/base.xml" />
    <logger name="org.springframework" level="OFF"/>
</configuration>

它打印默认系统信息，而不是启动噪音日志。（随着你想要的）

并且测试的依赖关系可以如下

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
</dependency>

首先：我知道，这不是一个真正的答案，但是评论太久了。

使用log4j依赖性在我的输出中没有太大变化。

            </plugin>
        </plugins>
    </build>
</project>

我的application.properties为空，因此那里没有日志配置。

我的测试

package com.example.demo;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT, properties = "logging.level.root=")
public class DemoApplicationTests
{

    @Test
    public void test()
    {
        System.out.println("Katzenbilder sind doof");
    }

}

使用logging.level.root=OFF在IntelliJ中运行测试会导致输出

  .   ____          _            __ _ _
 /\\ / ___'_ __ _ _(_)_ __  __ _ \ \ \ \
( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \

  '  |____| .__|_| |_|_| |_\__, | / / / /
 =========|_|==============|___/=/_/_/_/
 :: Spring Boot ::        (v2.0.4.RELEASE)

##### Optional[Hallo Welt]
##### Hallo Welt
Katzenbilder sind doof

Process finished with exit code 0

带有#####的两行是来自测试bean的System.out.println（）。

使用logging.level.root=INFO运行测试，我得到了预期的Spring日志消息的混乱情况。

我也只是出于验证的目的，将logging.level.root=INFO放在我的application.properties中，并在测试中将其放入OFF中。没有混乱，只有System.out.println（）消息。

Answer 3

您将需要在 \ test \ resources 目录中创建一个 logback-test.xml ，该文件的内容可以紧随其后

<?xml version="1.0" encoding="UTF-8"?>
<configuration />

为什么为空？

因为您现在不希望记录任何内容，因此-空配置。

如果您想了解更多具体信息，可以查看一些examples here

Answer 4

这似乎是log4j2的配置问题。请参考log4j2配置here的层次结构。

在您的情况下，log4j2最初是使用log4j2.properties下可用的log4j2.xml或src/main/resources配置的，因此INFO日志会打印在控制台上。仅当加载了测试类时，日志记录级别才会更改为OFF，只有在启动日志记录噪声已经打印后才能完成。

为避免任何启动日志噪音，请在log4j2.properties下添加log4j2.xml日志级别为src/test/resources的{{1}}或root不希望将其设置为ERROR，因为这也会抑制任何错误）。

我无法重现将启动日志写入OFF的错误。请检查您是否在stderr配置中将dest属性设置为err。这可以强制将启动日志写入log4j2。

编辑＃1

共享我在stderr下的log4j2.xml配置，以供参考。

在src/main/resources下，src/test/resources更改为<Root level="info">。

<Root level="error">

Answer 5

晚安，这里有很多答案。.关于日志级别的配置-似乎都有效。但是您的问题可能更多是使Maven构建更加嘈杂-为什么您不尝试将surefire的测试输出重定向到单独的文件中，每个测试一个文件？

https://maven.apache.org/surefire/maven-surefire-plugin/test-mojo.html#redirectTestOutputToFile

https://maven.apache.org/surefire/maven-failsafe-plugin/integration-test-mojo.html#redirectTestOutputToFile

这可以很好地在全球范围内完成，例如：

<pluginManagement>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-surefire-plugin</artifactId>
      <configuration>
        <redirectTestOutputToFile>true</redirectTestOutputToFile>
      </configuration>
  </plugin>
</pluginManagement>

如何在@SpringBootTest中启动期间防止记录噪音？
